Title (EN) WIND POWER GENERATION DEVICE
(FR) DISPOSITIF DE PRODUCTION D’ÉNERGIE ÉOLIENNE
(JA) 風力発電装置
Abstract:
(EN) The purpose of the present invention is to provide a wind power generation device that, when a plurality of control functions are executed simultaneously with pitch angle control, ensures stability by securely activating a control function that is to be given precedence and improves reliability. The present invention comprises: a blade that rotates by receiving air flow; a pitch angle control device that controls the pitch angle of the blade with a plurality of control functions; and an output adjustment means for the plurality of control functions of the pitch angle control device are provided. The pitch angle control device selects a control function, of the plurality of control functions, that has precedence on the basis of the state of the wind power generation device. The output adjustment means limits pitch angle output for at least one of the plurality of control functions other than the control function that has precedence.
(FR) Le but de la présente invention est de fournir un dispositif de production d'énergie éolienne qui, lorsqu'une pluralité de fonctions de commande sont exécutées simultanément avec une commande d'angle de calage, assure la stabilité en activant de manière sécurisée une fonction de commande qui doit être prioritaire et améliore la fiabilité. La présente invention comprend: une pale qui tourne en recevant un courant d'air; un dispositif de commande d'angle de calage qui commande l'angle de calage de la pale avec une pluralité de fonctions de commande; et un moyen de réglage de sortie pour la pluralité de fonctions de commande du dispositif de commande d'angle de calage. Le dispositif de commande d'angle de calage sélectionne une fonction de commande, parmi la pluralité de fonctions de commande, qui est prioritaire sur la base de l'état du dispositif de production d'énergie éolienne. Le moyen de réglage de sortie limite la sortie d'angle de calage pour au moins l'une de la pluralité de fonctions de commande autre que la fonction de commande qui est prioritaire.
(JA) ピッチ角制御で複数の制御機能を同時に実行する際に、優先すべき制御機能御を確実に動作させて安定性を確保し、信頼性を向上させる風力発電装置を提供することを目的とする。 風を受けて回転するブレードと、前記ブレードのピッチ角を複数の制御機能で制御するピッチ角制御装置と、前記ピッチ角制御装置における前記複数の制御機能に対する出力調整手段とを備え、前記ピッチ角制御装置は、風力発電装置の状態に基づいて前記複数の制御機能のうち優先する制御機能を選択し、前記出力調整手段は、前記優先する制御機能以外であって、前記複数の制御機能のいずれか一つ以上の制御機能についてピッチ角出力を制限する。
